[英]Rack fails with Rails when I try to upload file (using paper clip) on Ruby 1.9
我有一個Ruby on Rails應用程序,正在使用Ruby 1.9和Rails 2.3.4,我希望用戶上傳視頻,所以我安裝了Paperclip gem,但從Rack收到此錯誤。 它說它是“無效的字節序列”的事實使我懷疑它來自Ruby 1.9。
有任何想法嗎?
謝謝,
譚

看起來這里有一個答案:

本質上,解決方法是卸載Rails隨附的Rack版本並從github重新安裝gem。 當然,您可能想先在另一台機器上嘗試... :-)
